Overview ¶
Package domain contains the domain layer for the application.
The domain layer models the business dependent but application independent code. It contains the representation of the real world objects and processes that the application intends to model. This layer is also the centre of the application, meaning that it should not include any dependencies on the other three layers of the application.
The domain layer is usually quite thin, and sometimes only contains some struct and repository definitions. However, representations of business processes also live in this layer.
When deciding if code should go in the domain layer, a good starting question is "does this code model something that would exist in the business even if our application did not exist?". If the answer is yes, then it most likely lives here.

Variables ¶
var ( ErrNotFound = errors.New("not found") ErrAlreadyExists = errors.New("already exists") ErrInternal = errors.New("internal error") )
Errors to be returned by usecases and repository implementations.
Repositories should wrap these errors with sufficient context to enable debugging. Usecases are then responsible for recording the error using logging and/or tracing. Once recorded, usecases should return an unwrapped error with unambiguous meaning for the calling adapter to convert to an appropriate user-facing error response.
Additional errors should be defined here if the meaning of a particular error cannot be mapped to a specific error response.
